SIMPLE INGREDIENTS YOU NEED FOR THE SWEET YELLOW ONION BOIL?

You will need the following ingredients listed below to make the blooming onion boil (the exact measurements, nutritional value and full recipe are in the printable recipe card at the bottom of this post):

• Large sweet onion – can also use white onion or yellow onions however it will not yield exact same flavors.
• Unsalted butter – can also use vegan butter if desired
• Old Bay seasoning
• Cajun spice seasoning
• Sea salt and black pepper
• Garlic powder or crushed garlic
• Chili onion crunch from Trader Joe – this adds crispy bits.
• Optional – extra virgin olive oil, onion powder, lemon pepper, brown sugar, garlic clove, garam masala, etc.

HOW TO MAKE THE WHOLE ONION BOIL RECIPE

1. Preheat your oven to 375°F. Take a small melon baller and scoop out the top center of the onion (about ⅓ down) to create a “well” for the seasonings.
2. Place the onion on a sheet of aluminum foil. Add the butter into the middle of the onion well, mixing olive oil with Cajun seasoning and any optional seasonings. Pour the mixture over the butter so it drips down the sides of the onion. Sprinkle with a little extra salt.
3. Wrap the onion tightly in foil and place it in a baking dish or cast iron skillet to catch any drips. Roast for 1 hour on the center rack. Check for tenderness; if needed, bake another 10 minutes until fork-tender.
4. Optional: Turn the oven to broil. Open the foil, drizzle a bit more butter or olive oil, and sprinkle extra salt. Broil for 2-3 minutes, watching closely for a golden brown, caramelized top.
5. Peel away the outer layer and enjoy each soft, flavorful layer with an extra sprinkle of salt. Don’t forget to pour all the delicious juices from the foil over the onion for maximum flavor!

STORING LEFTOVER SWEET ONIONS

• Cool First: Let the onion cool completely before storing. This prevents moisture buildup in the container, keeping the onion fresh longer.
• Airtight Container: Place the leftover onion in an airtight container. It helps keep the flavors locked in and prevents the onion aroma from spreading in your fridge.
• Refrigeration: Store in the fridge for up to 3 days. While the flavors may deepen, the texture is best within the first couple of days.
• Reheating Tips: For best results, reheat in the oven or air fryer at 350°F for 10 minutes to warm through without making it too soft. Or, microwave for 30-second intervals until warm.
• Freezing: Avoid freezing, as it can cause the texture to become mushy. Fresh is best with this recipe!

TIPS AND TRICKS FOR BEST RESULTS

• Check the tenderness: If the onion isn’t fully tender after an hour, reseal and add a bit more time in the oven.
• Customize the Seasonings: Try it with smoked paprika, rosemary, or thyme for added flair!
• Broil Carefully: Watch closely during broiling to avoid burning – just golden and caramelized is the goal.

FAQS

CAN I USE DIFFERENT SEASONINGS?

Yes! Smoked paprika, rosemary, or thyme make amazing substitutes if you want to switch up the flavors.

HOW DO I KNOW WHEN THE ONION IS DONE?

The onion should be fork-tender with a slight jiggle and a golden caramelized top. If it’s still firm, keep it in the oven a bit longer.

CAN I PREPARE THIS ONION BOIL RECIPE AHEAD OF TIME?

Definitely! You can prep and season the onion, then wrap and refrigerate until ready to bake.

WHO STARTED THE VIRAL ONION BOIL RECIPE ON SOCIAL MEDIA?

The trend was kickstarted by TikToker @doll_mimi, who has charmed social media with this savory, simple onion recipe. If you’re looking for a unique, flavorful veggie snack, she’s got you covered!

DO I REALLY LOTS OF BUTTER IN THIS RECIPE?

Butter is key to that rich, melt-in-your-mouth flavor. However, you can substitute with olive oil or a vegan butter alternative if you prefer a lighter version or are going dairy-free.

WHY WRAP THE ENTIRE ONION IN FOIL?

Wrapping the onion in foil traps steam and juices, allowing the flavors to fully soak through without drying out the outer layers. This is the magic trick for that tender, caramelized effect.

IS THERE A WAY TO MAKE THIS ONION BOIL MORE CHEESY?

Yes! Add a sprinkle of shredded cheese, parmesan cheese, or even a slice of melty cheese on top before broiling. This “cheesy onion boil” option is a creamy twist that adds even more richness.
